Description: autotrace needs a rebuild due to the updated [extra]-packages imagemagick and pstoedit.

Additional info: Tested on architecture (i686)
* package version(s) imagemagick 6.4.0.9-1 autotrace 0.31.1-5 pstoedit 3.45-2
* config and/or log files etc.

Steps to reproduce: From the compilation run of autotrace:

*** Checking pstoedit existence TWICE(if needed) ***
*** This is the 1st check ***
checking for pstoedit-config... no
checking for PSTOEDIT - version >= 3.32.1... no
*** The pstoedit-config script installed by PSTOEDIT could not be found
*** If PSTOEDIT was installed in PREFIX, make sure PREFIX/bin is in
*** your path, or set the PSTOEDIT_CONFIG environment variable to the
*** full path to pstoedit-config.
*** The 1st check is failed. ***
*** This is the 2nd check ***
checking for pstoedit-config... (cached) no
checking for PSTOEDIT - version >= 3.32.0... no
*** The pstoedit-config script installed by PSTOEDIT could not be found
*** If PSTOEDIT was installed in PREFIX, make sure PREFIX/bin is in
*** your path, or set the PSTOEDIT_CONFIG environment variable to the
*** full path to pstoedit-config.
*** The 2nd check is failed.
